You're going to need a new amp any way it goes. Sorry . Depending on how the plate amp sits, its rating and other specs, you can get a replacement Bash plate amp (if it fits) for 150.00 at www.partsexpress.com. I've looked at the amp and it seems to be similar the only thing is that it will be mounted sideways to fit your present enclosure. It actually has more options than the original amp. Measure your plate amp diminsions against these: 11" W x 7" H x 3-1/2" D, if they are the same - this is your cheapest out for a DIY repair.
